its one cubic foot in one sec. actually its cu for cubic and sec for second, i hope that will help
1csec =gallon ?
1 cusec = 28.3 litres per second
1 cusec, or 1 cubic foot per second, would be 7.48 gallons per second.
It is actually called a cusec (cubic feet per second), not cusic. It is a volumetric unit for measuring the flow of liquids, equal to one cubic foot per second.1 ft3s-1 = 0.028316847m3s-1, 1 ft3s-1 = 1 cusec
1 Cusec is equal to 28.317 liters per second flow of water while 1 Gallon is equal to 3.785 liters.
1cusec= 28.317 liters/sec 1gallon = 3.78 liters therefore 1 cusec=28.317/3.78 = 7.491 litres
28 liters of water flow per second It is one cubic foot water flow per second. That is : A water flow of 28.317 liter per sec
1 cusec = 28.316847 liter/secon
However much you want. By suitably varying the thickness, you could, in theory cover the surface of the earth or even a larger area.The 'square feet' of area that it covers is 324/(depth in inches)
First - it is Cusec feet not cusic. 1 Cusec feet is short form of 1 Cubic feet per second. i.e., 1cu ft = 1 cubic ft/sec This unit is used to calculate flow rate of water usually in dams, flood, waterfalls, river etc.
A yard equals out to 3 feet, or 36 inches.
water covers a bigger area of earths surface in ration 3 : 1
